Hi guys, I had two USB drives plugged in to the Mac yesterday, one was a 2 TB external HDD and the other a memory stick. I wanted to create a boot drive for Lion on the USB stick so I opened up the Disk Utility, selected the drive, chose 1 Partition and set it to GUID Partition Table and clicked Apply. Oh crap, I've selected the HDD enclosure and not the USB stick... too late... so all the DVDs and CDs I've spent ages encoding, plus some other documents have all been wiped. Is there any way to recover the data as nothing has been written to the drive? I'm guessing as the HDD was formatted using NTFS or FAT32 on a WinXP box I would need to use a utility on that rather than a Mac recovery program? Many thanks for any assistance... Regards, Andy.
